Went here twice during my 4 days in Belgrade. No signs of the Krugher & Brent beers - just Amstel, Efes Draft and PlisPlus perhaps one or two other industrial pale lagers. Noisy, worn down and odd place.

Update: Sadly this place has declined in my view, doesn’t seem to have the selection anymore and less frequent concerts
Terrific small underground Belgrade blues bar. real local joint. Maybe the only place like it left in town. Live music often, great decor, bit of a biker’s bar. And they have all three of the Krugher & Brent beers, which is the only beer reason to come here.
Would be a cool place for you to visit if you’re passing through town, though it can be quite hard to find.
